Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method of manufacturing a window-opening envelope, and more particularly to a method of manufacturing a window-opening envelope using a sealed envelope.

(Prior art) Conventionally, in order to manufacture envelopes with a window, when punching out the outer shape according to the unfolded shape of the envelope, a window opening is punched out at a designated location, and the window opening is After manually adhering a light-transmitting sheet such as cellophane to the periphery, bags were made manually or using a bag-making machine.

(Problem to be solved by the invention) However, when producing window envelopes using the method described above, it is necessary to go through a special process going back to the outline punching process, so there is a long delay between receiving an order and completing the envelope. This process requires a long period of time, and each process requires special tools and jigs depending on the position and size of the window opening, resulting in high costs.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a method for manufacturing a window envelope that can be manufactured in a short period of time at low cost using a ready-made envelope.

(Means for Solving the Problems) In order to achieve the above object, the method for manufacturing an envelope with a window according to the present invention involves opening the opening of the envelope and holding a light-transmitting sheet that can be heat-sensitively bonded to a cutting temporary. After inserting the holding plate in a stacked manner and pressing a cutter with a cutting blade corresponding to the window shape toward the cutting receiving plate to form a window opening on one side of the envelope, the cutting receiving plate is extracted from the envelope. , the heating block that is in contact with the peripheral edge of the window opening is pressed toward the holding plate, and the holding plate and the heating block squeeze one side of the envelope and the light-transmitting sheet to bond them together.

(Function) According to the above-mentioned structure of the present invention, the process of forming a window opening on an existing envelope and adhering a light-transmitting sheet can be performed as a series of steps. Envelopes with a desired window opening can be easily and efficiently manufactured using the above method, and envelopes with a desired window opening can be obtained in a short period of time and at low cost. Problems can also be easily dealt with by replacing or changing the position of the cutter and heating block.

(Example) Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

As shown in FIG. 3, the window-opening envelope l has a window opening 3 formed at a suitable location on one side of a regular envelope 2 such as a standard-sized envelope, and the window opening 3 is filled with cellophane from the inside of the envelope 2. It is closed with a light-transmitting sheet 4 such as the like, and the light-transmitting sheet 4 is adhered to one side of the envelope 2 at the peripheral edge of the window opening 3.

The light transmitting sheet 4 is thermally bonded to the envelope 2 with a heat-sensitive adhesive layer formed on at least its peripheral edge.

Next, the general structure of the manufacturing apparatus for the windowed envelope 1 will be explained with reference to FIG.

A conveyance stage 5 is provided which sequentially and intermittently conveys the envelope 2 with its opening 2a facing one side of the conveyance path. 6 are arranged. This support plate 6 extends from the other side of the conveyance path to a position an appropriate distance before the opening 2a of the envelope 2.

At the tip of the support plate 6, a suction means 7 for suctioning the upper surface of the envelope 1 to open the opening 2a is disposed so as to be movable up and down. At the lower part of the conveyance path at the location where the support plate 6 is disposed, an elevating table 8 is disposed, and a movable table 9 movable in the conveying direction is installed thereon. On this movable base 9, a cutter 10 having a cutting blade 1l corresponding to the shape of the window opening 3 to be formed and a heating block 12 having a contact portion 13 for the peripheral edge of the window opening 3 are installed to move the movable base 9. are installed in parallel in the direction. Further, on one side of the conveyance path at the position where the support plate 6 is disposed, there is a cutting receiving plate 14 so as to face the opening 2a of the envelope 2 stopped at a position directly below the support plate 6.
and a holding plate 15 that can temporarily hold the light transmitting sheet 4 on the lower surface thereof. These cutting receiving plates 14 and holding vi. l
5 means that the envelopes 2 are stacked with the cutting plate l4 facing down.
They are disposed so as to be movable in a direction perpendicular to the transport direction so that they can be inserted into the container and taken out individually.

Next, the manufacturing process of the window envelope 1 using the above manufacturing apparatus will be explained based on FIGS. 1(a) to 1(d).

First, as shown in FIG. 1(a), the envelope 2 is transported to a position directly below the support plate 6 by the transport stage 5, and is positioned at a predetermined position according to the window shape position in the width direction of the envelope 2. Note that the window forming position in the longitudinal direction of the envelope 2 is
It is arbitrarily set depending on the holding position of the envelope 2 above. When the envelope 2 is positioned and stopped at a predetermined position directly below the support plate 6, the suction means 7 descends and suctions the upper surface of the envelope 2, and then rises as shown by arrow a, thereby opening the opening 2a of the envelope 2. It is opened wide, and then the cutting receiving plate 14 and the holding plate 5 holding the light transmitting sheet 4 on the underside are inserted into the envelope 2 from the opening 2a in a stacked state as shown by arrow b.

Next, as shown in Figure 1), after positioning the movable table 9 so that the cuck 10 is located directly below the support plate 6, the lifting table 8 is raised as shown by the arrow C, and is received by the cutting plate l4. A window opening 3 is formed on one surface of the lower side of the envelope 2 with the cutting blade 11 of the cutter 10.

Thereafter, the lifting table 8 is lowered as shown by the arrow d, and the cutting receiving plate 14 is pulled out from the envelope 2 as shown by the arrow e.

Then, the light transmitting sheet 4 held on the lower surface of the holding plate 15 faces the window opening 3 formed on one side of the envelope 2.

Next, as shown in FIG. 1(C), after positioning the movable table 9 so that the heating block l2 is directly below the support plate 6, the elevating table 8 is raised as shown by the arrow f, and the heating block l2
The window opening 3 of the envelope 2 is located between the contact portion 13 of the envelope 2 and the holding plate 15.
The peripheral edge of the light transmitting sheet 4 and the peripheral edge of the light transmitting sheet 4 are pressed together to bond them together by heating. Thereafter, the lifting platform 8 is lowered as shown by arrow g, and then the holding plate 15 is pulled out from the envelope 2 as shown by arrow h.

In this way, as shown in FIG. 1(d), a window opening 3 is formed in the envelope 2 and a light transmitting sheet 4 is adhered to the envelope 1.
is obtained, and then this window-opening envelope 1 is carried out by the transport stage 5, and the next envelope 2 is carried to a position directly below the support plate 6, and the above-mentioned operations are repeated to sequentially carry out the window-opening envelope processing. can be manufactured.

(Effects of the Invention) According to the method for manufacturing a windowed envelope of the present invention, the steps of forming a window opening in an existing envelope and bonding a light-transmitting sheet can be performed as a series of steps. It is possible to easily and efficiently produce envelopes with window openings using envelopes, and therefore envelopes with desired window openings can be obtained in a short period of time and at low cost, and it is also possible to change the size and position of the window. This also has the effect that it can be easily dealt with by replacing or changing the position of the cutter and heating block.
